Django在视图中获取foreignkey模型并在htm中显示

Question

所以我有两个模型：

class UserMeasurements(models.Model):
    user = models.CharField(max_length=20)
    time = models.DateTimeField(blank=True, null=True)
    set = models.ForeignKey(PhotoSets, models.DO_NOTHING)

    class Meta:
        managed = False
        db_table = 'user_measurements'

class PhotoSets(models.Model):
    image_dir = models.CharField(max_length=200)
    machine = models.ForeignKey(Machine, models.DO_NOTHING)
    set_id = models.AutoField(primary_key=True)
    photo_taken_time = models.DateTimeField(blank=True, null=True)

    class Meta:
        managed = False
        db_table = 'photo_sets'

在视图.py我有：

我试图在网页上显示每个用户测量图像的方向。 我检查了其他stackoverflow问题。但我还是想不通。在

提前谢谢。在
